The Box control makes it easy to upload, download, and manage files and folders within Box.com.

Syntax

Box

Remarks

The Box control provides a simple interface to working with Box.com. Capabilities include uploading and downloading files, strong encryption support, creating folders, moving and copying resources, and more.

Authentication

The control has the following defaults:

Below is a brief description of the different OAuthClientProfile and OAuthGrantType values that are supported by this control. For a more in-depth description of what needs to be set, refer to the service documentation.

Application Profile

This profile encompasses the most basic grant types that OAuth supports. When this profile is set, all the requests and response handling is done by the control. Depending on the grant type, this may involve launching a browser so a user can login to authenticate with a authorization server. It may also involve starting an embedded web server to receive a response from a redirect.

To start the authentication and authorization process, the Authorize method should be called. If the authorization and authentication was successful, then the OAuthAccessToken property will be populated. Additionally, if a refresh token was provided the OAuthRefreshToken property will be populated as well. These values of the fields are for informational purposes. The control will also cache these tokens along with when the OAuthAccessToken will be expired. When a method that makes requests to the service provider is called or the Authorize method is called the control will automatically check to see if the access token is expired. If it is, it will then automatically try to get a new OAuthAccessToken. If the Authorize method was not used and user interaction would be required, the control will throw an error which can be caught. When user interaction is needed depends on what grant type is set in the OAuthGrantType property. To force the component to only check the access token when the Authorize method is called, the OAuthAutomaticRefresh configuration setting can be set to false.

A brief description of the supported values for the OAuthGrantType property are below. For more information, see the service documentation.

Authorization Code

When using the Authorization Code grant type, the control will use an authorization code to get an access token. For this OAuthGrantType the control expects a OAuthClientId, OAuthClientSecret, OAuthServerAuthURL, and OAuthServerTokenURL to be set. When the Authorize method is called, the component will start the embedded web server and launch the browser so the user can authorize the application. Once the user authorizes, the service provider will redirect them to the embedded web server and the control will parse the authorization code, setting the OAuthAuthorizationCode property, from the redirect. Immediately, the control will make a request to the token server to exchange the authorization code for an access token. The token server will return an access token and possibly a refresh token. If the OAuthRefreshToken property is set, or a refresh token is cached, then the control will not launch the browser and use the refresh token in its request to the token server instead of an authorization code.

Example: Box box = new Box(); box.OAuth.ClientProfile = OAuthClientProfiles.cocpApplication; box.OAuth.GrantType = OAuthGrantTypes.cogtAuthorizationCode; box.OAuth.ClientId = CLIENT_ID; box.OAuth.ClientSecret = CLIENT_SECRET; box.Config("OAuthWebServerPort=PORT"); // http://localhost:PORT needs to be a registered redirect URL for the app box.Authorize();

Client Credentials

When using the Client Credentials grant type, the control will act as a service instead of authorizing and authenticating as a user. This allows for the control to avoid user interaction. This is typically used when running in an application that can not have user access. This grant type requires additional set up to be done in the service providers portal before it can be used. For this OAuthGrantType the control expects a OAuthClientId, OAuthClientSecret, and OAuthServerTokenURL to be set. When the Authorize method is called, the component will make a request to the token server for an access token. The token server will return an access token if the application has the authorization to do so. When this access token is expired, the component will automatically (see above for detailed description) make a new request to get a fresh one.

Web Profile

External OAuth Support

Bearer ACCESS_TOKEN_VALUE

Assign this value to the Authorization property before attempting any operations. Setting the Authorization property will cause the control to ignore the values set in the OAuth property.

For Example: Oauth oauth = new Oauth(); oauth.GrantType = OauthGrantTypes.ogtAuthorizationCode; oauth.ClientId = "CLIENT_ID"; oauth.ClientSecret = "CLIENT_SECRET"; oauth.ServerAuthURL = "https://app.box.com/api/oauth2/authorize"; oauth.ServerTokenURL = "https://api.box.com/oauth2/token"; oauth.WebServerPort = PORT; // http://localhost:PORT needs to be a registered redirect URL for the app box.Authorization = oauth.GetAuthorization(); Consult the documentation for the service for more information about supported scope values and more details on OAuth authentication.

Listing Resources

ListResources lists resources within the specified folder. Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resource* properties. // ResourceList event handler. box.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; do { box.ListResources("d:123456"); for (int i = 0; i < box.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(box.ResourceMarker));

Downloading Files

The DownloadFile method downloads file resources.

If LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: box.LocalFile = "../MyFile.zip"; box.DownloadFile(box.Resources[0].Id);

Resuming Downloads

The control also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; box.LocalFile = downloadFile; box.DownloadFile(box.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file box.StartByte = new FileInfo(downloadFile).Length; box.DownloadFile(box.Resources[0].Id);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the control creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. box.LocalFile = "../MyFile.zip"; box.EncryptionPassword = "password"; box.DownloadFile(box.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file box.StartByte = new FileInfo(box.Config("DownloadTempFile")).Length; box.DownloadFile(box.Resources[0].Id);

Uploading Files

The UploadFile method uploads new file resources.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

Box offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files (must be larger than 20 MB), uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the control uses the simple upload mechanism. When doing a simple upload, the HashSimpleUploads setting is applicable. box.LocalFile = "../MyFile.zip"; box.UploadFile("MyFile.zip", "");

Resumable

To enable resumable uploads set UseResumableUpload to . This is recommended for large files (must be larger than 20 MB). The control will automatically fragment the specified file into smaller pieces and upload each individually.

When UseResumableUpload is set to and UploadFile is called, a resumable upload session is started by the control. ResumeURL is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The control also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that ResumeURL is populated (if the same instance of the control is used, it should already be populated, and no special action should be needed). Call PollUploadStatus to populate the correct values for StartByte and UploadFragmentSize. Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. PollUploadStatus may be used to check the status of a resumable upload, including when it will expire (which is stored in the UploadExpDate configuration setting). An interrupted upload can be aborted explicitly using the AbortUpload method. box.LocalFile = "../MyFile.zip"; box.UploadFile("MyFile.zip", ""); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. box.UploadFile("MyFile.zip", "");

Additional Functionality

The Box control offers advanced functionality beyond simple uploads and downloads. For instance:

• Encrypt and decrypt files using the EncryptionAlgorithm and EncryptionPassword properties.
• Basic file and folder manipulation and organization using methods such as CopyResource, CreateFolder, DeleteResource, MoveResource, and RestoreResource.
• Support for resource sharing using CreateLink and RevokeLink.

UseResumableUpload Property (Box Control)

Whether to use resumable uploads.

Syntax

boxcontrol.UseResumableUpload[=boolean]

Default Value

False

Remarks

This property controls whether simple or resumable uploads are used when UploadFile is called. The default value is (simple uploads are used).

Refer to UploadFile for more information.

This property is not available at design time.

Data Type

Boolean

VersionMarker Property (Box Control)

A marker indicating what page of file versions to return next.

Syntax

boxcontrol.VersionMarker[=string]

Default Value

""

Remarks

This property will be populated when ListVersions is called if the results are paged and there are more pages. To list all file versions, continue to call ListVersions until this property returns empty string.

Refer to ListVersions for more information.

This property is not available at design time.

Data Type

String

AbortUpload Method (Box Control)

Aborts the current resumable upload session.

Syntax

boxcontrol.AbortUpload 

Remarks

This method aborts the current resumable upload session specified by ResumeURL. It may be called if the current resumable upload has been interrupted and will not be resumed.

AddQueryParam Method (Box Control)

Adds a query parameter to the QueryParams properties.

Syntax

boxcontrol.AddQueryParam Name, Value

Remarks

This method is used to add a query parameter to the QueryaParam* properties. Name specifies the name of the parameter, and Value specifies the value of the parameter.

All specified Values will be URL encoded by the control automatically. Consult the service documentation for details on the available parameters.

Authorize Method (Box Control)

Get the authorization string required to access the protected resource.

Syntax

boxcontrol.Authorize 

Remarks

This method is used to get an access token that is required to access the protected resource. The method will act differently based on what is set in the OAuthClientProfile property and the OAuthGrantType property. This method is not to be used in conjunction with the Authorization property. It should instead be used when setting the OAuth* properties.

For more information, see the introduction section.

CalcAuthorization Method (Box Control)

Calculates the Authorization header based on provided credentials.

Syntax

boxcontrol.CalcAuthorization 

Remarks

This method calculates the Authorization value using the values provided in AuthScheme, User and Password.

In most cases this method does not need to be called. The control will automatically calculate any required authorization values when a method is called such as Get or Post.

This method may be useful in cases where the Authorization value needs to be calculated prior to sending a request.

Config Method (Box Control)

Sets or retrieves a configuration setting.

Syntax

boxcontrol.Config ConfigurationString

Remarks

Config is a generic method available in every control. It is used to set and retrieve configuration settings for the control.

These settings are similar in functionality to properties, but they are rarely used. In order to avoid "polluting" the property namespace of the control, access to these internal properties is provided through the Config method.

To set a configuration setting named PROPERTY, you must call Config("PROPERTY=VALUE"), where VALUE is the value of the setting expressed as a string. For boolean values, use the strings "True", "False", "0", "1", "Yes", or "No" (case does not matter).

To read (query) the value of a configuration setting, you must call Config("PROPERTY"). The value will be returned as a string.

CopyResource Method (Box Control)

Copies a resource.

Syntax

boxcontrol.CopyResource ResourceId, ParentId, NewName

Remarks

This method copies the resource specified by ResourceId to the folder specified by ParentId. The Id of the newly-copied resource is returned.

NewName specifies the name of the copied resource; if empty, the resource's original name is used. ParentId can also be empty, in which case the resource is copied to the root folder.

NewName must be no longer than 255 characters; may not contain /, \, non-printable ASCII characters, or trailing whitespace; and cannot be one of the special names . or ...

Note that copy operations for folders with greater than 500 children (counted recursively) are performed asynchronously; the server will return the Id of the newly-copied folder resource immediately while continuing to perform the copy operation over time. There is no way to monitor an asynchronous copy operation.

CreateFolder Method (Box Control)

Creates a new folder resource.

Syntax

boxcontrol.CreateFolder FolderName, ParentId

Remarks

This method creates a new folder resource named FolderName in the folder specified by ParentId. The Id of the newly-created folder resource is returned.

FolderName must be no longer than 255 characters; may not contain /, \, non-printable ASCII characters, or trailing whitespace; and cannot be one of the special names . or ...

ParentId can be empty, in which case the folder is created in the root folder.

CreateLink Method (Box Control)

Creates a shared link.

Syntax

boxcontrol.CreateLink ResourceId

Remarks

This method creates a shared link for the resource specified by ResourceId. The URL of the shared link is returned.

Only one shared link may be active at a time for each resource; calling this method for a resource that already has an active shared link will update the shared link's settings without changing its URL.

The following configuration settings may be used to configure the shared link:

• CreateLinkAccess
• CreateLinkAllowDownloads
• CreateLinkExpiration
• CreateLinkPassword

CreateMetadata Method (Box Control)

Creates a new metadata container on a resource.

Syntax

boxcontrol.CreateMetadata ResourceId, Scope, Schema

Remarks

This method creates a new metadata container on the resource specified by ResourceId. The metadata container is created using the specified Scope and Schema.

Scope must be global or an enterprise-specific scope of the form enterprise_<EnterpriseId>. If Scope is empty, global is used.

If Scope is global, then Schema must be properties; otherwise, it must be the name of an existing metadata container schema owned by the enterprise identified in Scope. If Schema is empty, properties is used.

When this method is called, any Metadata* items that satisfy all of the following constraints will be added to the new metadata container immediately (assuming the server returns no errors):

• Their MetadataModOp properties must be set to 1 (opAdd).
• Their MetadataResourceId properties must be empty, or must match the value provided for ResourceId.
• Their MetadataContainerScope properties must be empty, or must match the value provided for Scope.
• Their MetadataContainerSchema properties must be empty, or must match the value provided for Schema.

All applicable metadata items will have their MetadataModOp property reset to 0 (opNone) if the request succeeds.

Metadata Notes

Box's Metadata architecture consists of two entities: metadata items, and metadata containers (which Box calls "metadata templates").

A metadata item is just a name-value pair held by a metadata container. Its name may be up to 256 characters long, cannot begin with the $ character, and must be unique within the container.

A metadata container holds metadata items, and is associated with a single resource. All metadata containers must be created using a metadata container schema, which describes the possible metadata items the container may hold. Containers are uniquely identified (per-resource) by a schema path like /Scope/Schema (ergo, a resource cannot have multiple containers of the same schema).

Box provides a general-use schema, /global/properties, that functions as an unrestricted key-value store that will accept any metadata item. Enterprises can also create custom schemas, /enterprise_<EnterpriseId>/Schema, that only allow predefined metadata items (with specific data types) to be added.

See the following methods for more information: CreateMetadata, ListMetadata, UpdateMetadata, and DeleteMetadata.

Note that metadata is only usable on resources owned by paid Box accounts. string resId = "f:09876"; // Create an instance of the default metadata container ("/global/properties") with a couple of metadata // items in it, and associate it with the specified resource. (Note that we're assuming that the given // resource doesn't already have an instance of the default metadata container associated with it.) box.Metadata.Add(new BoxMetadata() { Name = "num1", Value = "123", ModOp = BoxMetadataModOps.opAdd }); box.Metadata.Add(new BoxMetadata() { Name = "text1", Value = "abc", ModOp = BoxMetadataModOps.opAdd }); // All of the control's metadata-related methods all empty string to be passed to their Scope and Schema // parameters, in which case "global" and "properties" will be used, respectively. (The exception is the // ListMetadata() method, which interprets empty Scope and Schema values in a different way; refer to the // ListMetadata() documentation for more information.) box.CreateMetadata(resId, "", ""); // Some time later, imagine you wish to update the metadata items held by the default container on that // resource. Always call ListMetadata() first so that control has the latest metadata loaded. box.ListMetadata(resId, "global", "properties"); // Now that the control has the latest metadata items loaded for the default container on the given // resource, we can modify what we wish to, setting the ModOp fields appropriately. box.Metadata[0].Value = "456"; // Update the value of the "num1" item. box.Metadata[0].ModOp = BoxMetadataModOps.opReplace; box.Metadata[1].ModOp = BoxMetadataModOps.opRemove; // Remove the "text1" item. // Add a new "text2" item. box.Metadata.Add(new BoxMetadata() { Name = "text2", Value = "def", ModOp = BoxMetadataModOps.opAdd }); // Now commit the updates. Our example performs very simple updates, but you can build a very complex // update scenario using some of the other ModOp values. Refer to the UpdateMetadata() documentation // for more information. box.UpdateMetadata(resId, "", ""); // Finally, this will remove the entire default metadata container from the given resource. box.DeleteMetadata(resId, "", "");

CreatePreviewLink Method (Box Control)

Creates a preview link.

Syntax

boxcontrol.CreatePreviewLink FileId

Remarks

This method creates a preview link for the file resource specified by FileId. The URL of the preview link is returned. Preview links are suitable for embedding in iframes.

Note that preview links expire after 60 seconds, and the preview session expires after 60 minutes. Not all files support previewing.

DeleteMetadata Method (Box Control)

Deletes a metadata container from a resource.

Syntax

boxcontrol.DeleteMetadata ResourceId, Scope, Schema

Remarks

This method deletes the metadata container specified by Scope and Schema from the resource specified by ResourceId. All metadata items held by the specified container are also deleted (individual metadata items can be deleted from a container using the UpdateMetadata method; refer to its documentation for more information).

Scope must be global or an enterprise-specific scope of the form enterprise_<EnterpriseId>. If Scope is empty, global is used.

If Scope is global, then Schema must be properties; otherwise, it must be the name of an existing metadata container schema owned by the enterprise identified in Scope. If Schema is empty, properties is used.

Metadata Notes

Box's Metadata architecture consists of two entities: metadata items, and metadata containers (which Box calls "metadata templates").

A metadata item is just a name-value pair held by a metadata container. Its name may be up to 256 characters long, cannot begin with the $ character, and must be unique within the container.

A metadata container holds metadata items, and is associated with a single resource. All metadata containers must be created using a metadata container schema, which describes the possible metadata items the container may hold. Containers are uniquely identified (per-resource) by a schema path like /Scope/Schema (ergo, a resource cannot have multiple containers of the same schema).

Box provides a general-use schema, /global/properties, that functions as an unrestricted key-value store that will accept any metadata item. Enterprises can also create custom schemas, /enterprise_<EnterpriseId>/Schema, that only allow predefined metadata items (with specific data types) to be added.

See the following methods for more information: CreateMetadata, ListMetadata, UpdateMetadata, and DeleteMetadata.

Note that metadata is only usable on resources owned by paid Box accounts. string resId = "f:09876"; // Create an instance of the default metadata container ("/global/properties") with a couple of metadata // items in it, and associate it with the specified resource. (Note that we're assuming that the given // resource doesn't already have an instance of the default metadata container associated with it.) box.Metadata.Add(new BoxMetadata() { Name = "num1", Value = "123", ModOp = BoxMetadataModOps.opAdd }); box.Metadata.Add(new BoxMetadata() { Name = "text1", Value = "abc", ModOp = BoxMetadataModOps.opAdd }); // All of the control's metadata-related methods all empty string to be passed to their Scope and Schema // parameters, in which case "global" and "properties" will be used, respectively.

Our example performs very simple updates, but you can build a very complex // update scenario using some of the other ModOp values. Refer to the UpdateMetadata() documentation // for more information. box.UpdateMetadata(resId, "", ""); // Finally, this will remove the entire default metadata container from the given resource. box.DeleteMetadata(resId, "", "");

DeleteResource Method (Box Control)

Trashes or permanently deletes a resource.

Syntax

boxcontrol.DeleteResource ResourceId

Remarks

This method trashes the resource specified by ResourceId. If the resource is already in the trash, it is permanently deleted instead.

To list trashed resources, call ListResources and pass trash for the FolderId method parameter.

DownloadFile Method (Box Control)

Downloads a file resource.

Syntax

boxcontrol.DownloadFile FileId

Remarks

This method downloads the file resource specified by FileId.

The DownloadType property can be used to control whether this method downloads the file contents (default) or a file thumbnail. Refer to DownloadType for more information.

If LocalFile is set, the file will be saved to the specified location; otherwise, the file data will be held by ResourceData.

To download and decrypt an encrypted file, set EncryptionAlgorithm and EncryptionPassword before calling this method.

Download Notes

In the simplest use-case, downloading a file looks like this: box.LocalFile = "../MyFile.zip"; box.DownloadFile(box.Resources[0].Id);

Resuming Downloads

The control also supports resuming failed downloads by using the StartByte property. If a download is interrupted, set StartByte to the appropriate offset before calling this method to resume the download. string downloadFile = "../MyFile.zip"; box.LocalFile = downloadFile; box.DownloadFile(box.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially downloaded file box.StartByte = new FileInfo(downloadFile).Length; box.DownloadFile(box.Resources[0].Id);

Resuming Encrypted File Downloads

Resuming encrypted file downloads is only supported when LocalFile was set in the initial download attempt.

If LocalFile is set when beginning an encrypted download, the control creates a temporary file in TempPath to hold the encrypted data until the download is complete. If the download is interrupted, DownloadTempFile will be populated with the path of the temporary file that holds the partial data.

To resume, DownloadTempFile must be populated, along with StartByte, to allow the remainder of the encrypted data to be downloaded. Once the encrypted data is downloaded it will be decrypted and written to LocalFile. box.LocalFile = "../MyFile.zip"; box.EncryptionPassword = "password"; box.DownloadFile(box.Resources[0].Id); //The transfer is interrupted and DownloadFile() above fails. Later, resume the download: //Get the size of the partially download temp file box.StartByte = new FileInfo(box.Config("DownloadTempFile")).Length; box.DownloadFile(box.Resources[0].Id);

GetAccountInfo Method (Box Control)

Gets information about the current user's account and space usage.

Syntax

boxcontrol.GetAccountInfo 

Remarks

This method gets information about the current user's account and space usage, populating the Account* properties.

GetResourceInfo Method (Box Control)

Gets information about a specific resource.

Syntax

boxcontrol.GetResourceInfo ResourceId

Remarks

This method gets information about the resource specified by ResourceId.

ResourceId can be empty string to get information about the root folder.

Calling this method will fire the ResourceList event, and will populate the Resource* properties with a single item (clearing any previously-held items in the process).

Interrupt Method (Box Control)

Interrupt the current method.

Syntax

boxcontrol.Interrupt 

Remarks

If there is no method in progress, Interrupt simply returns, doing nothing.

ListMetadata Method (Box Control)

Lists the metadata items for a resource.

Syntax

boxcontrol.ListMetadata ResourceId, Scope, Schema

Remarks

This method lists the metadata items for the resource specified by ResourceId. If Scope and Schema are both empty, metadata items from all metadata containers associated with the resource are returned. Otherwise, only the items in the container specified by Scope and Schema are returned.

When non-empty, Scope and Schema must either be global and properties (respectively); or enterprise_<EnterpriseId> and the name of an existing metadata container within that scope on the specified resource.

Calling this method will fire the MetadataList event once for each metadata item, and will populate the Metadata* properties (clearing any previously-held items in the process).

Metadata Notes

Box's Metadata architecture consists of two entities: metadata items, and metadata containers (which Box calls "metadata templates").

A metadata item is just a name-value pair held by a metadata container. Its name may be up to 256 characters long, cannot begin with the $ character, and must be unique within the container.

A metadata container holds metadata items, and is associated with a single resource. All metadata containers must be created using a metadata container schema, which describes the possible metadata items the container may hold. Containers are uniquely identified (per-resource) by a schema path like /Scope/Schema (ergo, a resource cannot have multiple containers of the same schema).

Box provides a general-use schema, /global/properties, that functions as an unrestricted key-value store that will accept any metadata item. Enterprises can also create custom schemas, /enterprise_<EnterpriseId>/Schema, that only allow predefined metadata items (with specific data types) to be added.

See the following methods for more information: CreateMetadata, ListMetadata, UpdateMetadata, and DeleteMetadata.

Note that metadata is only usable on resources owned by paid Box accounts. string resId = "f:09876"; // Create an instance of the default metadata container ("/global/properties") with a couple of metadata // items in it, and associate it with the specified resource. (Note that we're assuming that the given // resource doesn't already have an instance of the default metadata container associated with it.) box.Metadata.Add(new BoxMetadata() { Name = "num1", Value = "123", ModOp = BoxMetadataModOps.opAdd }); box.Metadata.Add(new BoxMetadata() { Name = "text1", Value = "abc", ModOp = BoxMetadataModOps.opAdd }); // All of the control's metadata-related methods all empty string to be passed to their Scope and Schema // parameters, in which case "global" and "properties" will be used, respectively.

Our example performs very simple updates, but you can build a very complex // update scenario using some of the other ModOp values. Refer to the UpdateMetadata() documentation // for more information. box.UpdateMetadata(resId, "", ""); // Finally, this will remove the entire default metadata container from the given resource. box.DeleteMetadata(resId, "", "");

ListResources Method (Box Control)

Lists resources.

Syntax

boxcontrol.ListResources FolderId

Remarks

This method lists resources within the folder specified by FolderId.

FolderId can be empty string to list resources in the root folder, or trash to list trashed resources.

Calling this method will fire the ResourceList event once for each resource, and will also populate the Resource* properties.

If there are still more resources available to list when this method returns, the ResourceMarker property will be populated. Continue to call this method until ResourceMarker is empty to accumulate all pages of results in the Resource* properties.

The MaxResults configuration setting can be used to control the maximum number of results to return at once. // ResourceList event handler. box.OnResourceList += (s, e) => { Console.WriteLine(e.Name); }; do { box.ListResources("d:123456"); for (int i = 0; i < box.Resources.Count; i++) { // Process resources here. } } while (!string.IsNullOrEmpty(box.ResourceMarker));

ListVersions Method (Box Control)

Lists previous versions of a file resource.

Syntax

boxcontrol.ListVersions FileId

Remarks

This method lists previous versions of the file resource specified by FileId. The current version is not included in the results.

Calling this method will fire the ResourceList event once for each file version, and will also populate the Resource* properties.

If there are still more file versions available to list when this method returns, the VersionMarker property will be populated. Continue to call this method until VersionMarker is empty to accumulate all pages of results in the Resource* properties.

Note that Box only returns certain resource details when listing file versions; this is a limitation of the Box API that cannot be changed. Specifically, the following properties are returned:

• ResourceCreatedTime
• ResourceHash
• ResourceId (populated by the control for convenience)
• ResourceModifiedBy
• ResourceModifiedTime
• ResourceName
• ResourceSize
• ResourceType (always 0 (brtFile))
• ResourceVersionId

The MaxResults configuration setting can be used to control the maximum number of results to return at once.

Note that Box only tracks file versions for paid accounts. // ResourceList event handler. box.OnResourceList += (s, e) => { Console.WriteLine(e.Name + ", Version: " + e.VersionId); }; do { box.ListVersions("f:09876"); for (int i = 0; i < box.Resources.Count; i++) { // Process resource versions here. } } while (!string.IsNullOrEmpty(box.VersionMarker));

LockFile Method (Box Control)

Locks a file resource.

Syntax

boxcontrol.LockFile FileId, Expiration, AllowDownloading

Remarks

This method locks the file resource specified by FileId to prevent others from modifying it.

Expiration may be set to an appropriately-formatted timestamp to specify an expiration time for the file lock. If Expiration is empty, the file lock will never expire. Timestamps are formatted according to RFC 3339.

AllowDownloading specifies whether others should still be allowed to download the file while it's locked.

MoveResource Method (Box Control)

Moves a resource.

Syntax

boxcontrol.MoveResource ResourceId, ParentId, NewName

Remarks

This method moves the resource specified by ResourceId to the folder specified by ParentId.

NewName specifies the new name of the resource; if empty, the resource's original name is used. ParentId can also be empty, in which case the resource is moved to the root folder.

NewName must be no longer than 255 characters; may not contain /, \, non-printable ASCII characters, or trailing whitespace; and cannot be one of the special names . or ...

When moving a folder that contains many items, keep in mind that Box always performs move operations synchronously (whereas copy operations are performed asynchronously for folders that contain more than 500 items). This method will block until the move operation completes, unless the control times out the request based on the current value of Timeout.

PollUploadStatus Method (Box Control)

Gets the status of the current resumable upload session.

Syntax

boxcontrol.PollUploadStatus 

Remarks

This method retrieves the status of the resumable upload session specified by ResumeURL.

After calling this method, the StartByte property and UploadExpDate and UploadFragmentSize configuration settings will be populated.

PromoteVersion Method (Box Control)

Promotes a previous file resource version to be the current version.

Syntax

boxcontrol.PromoteVersion FileId, VersionId

Remarks

This method promotes a previous version of the file resource specified by FileId to be the current version.

VersionId specifies the version that should be promoted. Box will make a copy of it to use as the new version.

Note that Box only tracks file versions for paid accounts.

Reset Method (Box Control)

Resets the control to its initial state.

Syntax

boxcontrol.Reset 

Remarks

This method resets the control to its initial state.

RestoreResource Method (Box Control)

Restores a resource from the trash.

Syntax

boxcontrol.RestoreResource ResourceId, ParentId, NewName

Remarks

This method restores the resource specified by ResourceId from the trash.

Box will always ignore ParentId and/or NewName in favor of restoring a trashed resource to its original location with its original name if possible. The ParentId and NewName parameters are only considered if one or both of the following are true:

• The original parent folder resource no longer exists (in which case ParentId will be used instead, if not empty).
• The original resource name is already in use in the original (or new) parent folder (in which case NewName will be used instead, if not empty).

RevokeLink Method (Box Control)

Revokes a shared link.

Syntax

boxcontrol.RevokeLink ResourceId

Remarks

This method revokes the shared link for the resource specified by ResourceId. If the specified resource doesn't have a shared link active, this method does nothing.

Search Method (Box Control)

Searches for resources that match the specified query.

Syntax

boxcontrol.Search Query

Remarks

This method searches for resources that match the given Query, which the server will match against names, descriptions, file contents, etc.

Advanced searches can be performed by adding additional query parameters using the AddQueryParam method. Here are examples of some of the more common query parameters:

Calling this method will fire the ResourceList event once for each search result, and will also populate the Resource* properties.

If there are still more search results available to list when this method returns, the SearchMarker property will be populated. Continue to call this method until SearchMarker is empty to accumulate all pages of results in the Resource* properties.

The MaxSearchResults configuration setting can be used to control the maximum number of results to return at once.

SendCustomRequest Method (Box Control)

Sends a custom request to the Box API.

Syntax

boxcontrol.SendCustomRequest HttpMethod, RequestPath, RequestBody

Remarks

This method can be used to send arbitrary requests to the Box API.

Valid values for HttpMethod are:

• GET (default if empty)
• HEAD
• POST
• PUT
• DELETE

The value passed for RequestPath must already be URL-encoded in a manner acceptable to the Box API. The RequestBody parameter may be empty if not needed.

Usage

When this method is called, the control does the following:

1. Builds a request URL, including query parameters, as follows:
   • The specified RequestPath is appended to the Box API endpoint, https://api.box.com/2.0.
   • All query parameters in the QueryParam* properties are added to the request URL.
2. Sends the request using the specified HttpMethod, the request URL build in step 1, the header information held by Authorization and OtherHeaders, and the given RequestBody (if non-empty).
3. Stores the response headers in the ParsedHeader* properties, and the response body in the specified LocalFile, or ResourceData (using the same logic as DownloadFile).

If the response body is JSON data, the XPath, XText, and other X* configuration settings can then be used to navigate and extract information from it.

UnlockFile Method (Box Control)

Unlocks a locked file resource.

Syntax

boxcontrol.UnlockFile FileId

Remarks

This method unlocks a file resource, specified by FileId, previously locked by the current account.

UpdateMetadata Method (Box Control)

Updates the metadata items for an existing metadata container.

Syntax

boxcontrol.UpdateMetadata ResourceId, Scope, Schema

Remarks

This method updates the metadata items for an existing metadata container, specified by Scope and Schema, that is associated with the resource specified by ResourceId.

Scope must be global or an enterprise-specific scope of the form enterprise_<EnterpriseId>. If Scope is empty, global is used.

If Scope is global, then Schema must be properties; otherwise, it must be the name of an existing metadata container schema owned by the enterprise identified in Scope. If Schema is empty, properties is used.

Each item represented by the Metadata* properties has a MetadataModOp property which can be set to one of the following values:

When this method is called, the control will iterate through the Metadata* properties and build up a modification request that includes the specified operation for each applicable metadata item. For a metadata item to be included in the request, all of the following must be true:

• Its MetadataModOp property must not be set to 0 (opNone).
• Its MetadataResourceId property must be empty, or must match the value provided for ResourceId.
• Its MetadataContainerScope property must be empty, or must match the value provided for Scope.
• Its MetadataContainerSchema property must be empty, or must match the value provided for Schema.

A couple of things to keep in mind regarding metadata item modification operations:

• Box applies each modification operation in the request sequentially, so the order in which they are transmitted is significant (though it may not impact all use-cases).
  • By default, the control transmits the applicable modification operations based on the order of the Metadata* items.
  • To specify an explicit order, the MetadataUpdateOrder configuration setting can be set to a comma-separated list of Metadata* item indices.
• Box guarantees overall atomicity for the request; if the modification operation for any one item fails, then the whole request fails, and no changes are made.
• If the request completes successfully, the control will reset all affected metadata items' MetadataModOp properties back to 0 (opNone).

Usage

ListMetadata must be called before using this method in order to populate the Metadata* properties with a resource's existing metadata items. (When creating new metadata items, calling ListMetadata first is optional, but still recommended to ensure that the control reflects the latest information.)

To create new metadata items, add new items to the Metadata* properties by incrementing the MetadataCount property as necessary.

For each metadata item being created or updated, set its properties to the desired values. The MetadataModOp property should be set to a value other than 0 (opNone).

Once the metadata items have been set up as desired, call this method.

Metadata Notes

Box's Metadata architecture consists of two entities: metadata items, and metadata containers (which Box calls "metadata templates").

A metadata item is just a name-value pair held by a metadata container. Its name may be up to 256 characters long, cannot begin with the $ character, and must be unique within the container.

A metadata container holds metadata items, and is associated with a single resource. All metadata containers must be created using a metadata container schema, which describes the possible metadata items the container may hold. Containers are uniquely identified (per-resource) by a schema path like /Scope/Schema (ergo, a resource cannot have multiple containers of the same schema).

Box provides a general-use schema, /global/properties, that functions as an unrestricted key-value store that will accept any metadata item. Enterprises can also create custom schemas, /enterprise_<EnterpriseId>/Schema, that only allow predefined metadata items (with specific data types) to be added.

See the following methods for more information: CreateMetadata, ListMetadata, UpdateMetadata, and DeleteMetadata.

Note that metadata is only usable on resources owned by paid Box accounts. string resId = "f:09876"; // Create an instance of the default metadata container ("/global/properties") with a couple of metadata // items in it, and associate it with the specified resource. (Note that we're assuming that the given // resource doesn't already have an instance of the default metadata container associated with it.) box.Metadata.Add(new BoxMetadata() { Name = "num1", Value = "123", ModOp = BoxMetadataModOps.opAdd }); box.Metadata.Add(new BoxMetadata() { Name = "text1", Value = "abc", ModOp = BoxMetadataModOps.opAdd }); // All of the control's metadata-related methods all empty string to be passed to their Scope and Schema // parameters, in which case "global" and "properties" will be used, respectively. (The exception is the // ListMetadata() method, which interprets empty Scope and Schema values in a different way; refer to the // ListMetadata() documentation for more information.) box.CreateMetadata(resId, "", ""); // Some time later, imagine you wish to update the metadata items held by the default container on that // resource. Always call ListMetadata() first so that control has the latest metadata loaded. box.ListMetadata(resId, "global", "properties"); // Now that the control has the latest metadata items loaded for the default container on the given // resource, we can modify what we wish to, setting the ModOp fields appropriately. box.Metadata[0].Value = "456"; // Update the value of the "num1" item. box.Metadata[0].ModOp = BoxMetadataModOps.opReplace; box.Metadata[1].ModOp = BoxMetadataModOps.opRemove; // Remove the "text1" item. // Add a new "text2" item. box.Metadata.Add(new BoxMetadata() { Name = "text2", Value = "def", ModOp = BoxMetadataModOps.opAdd }); // Now commit the updates. Our example performs very simple updates, but you can build a very complex // update scenario using some of the other ModOp values. Refer to the UpdateMetadata() documentation // for more information. box.UpdateMetadata(resId, "", ""); // Finally, this will remove the entire default metadata container from the given resource. box.DeleteMetadata(resId, "", "");

UpdateResource Method (Box Control)

Updates a resource.

Syntax

boxcontrol.UpdateResource ResourceId

Remarks

This method updates the information for the resource specified by ResourceId. For file resources, the file data can optionally be updated as well.

Usage

There must be an item in the Resource* properties whose ResourceId property matches the given ResourceId parameter before this method is called.

1. If necessary, call GetResourceInfo or ListResources to ensure an item with the resource's latest information is present in the Resource* properties.
2. Modify the item's Resource* properties as desired; the following properties are supported:
   • ResourceDescription
   • ResourceName (the same restrictions as described in UploadFile apply)
   • ResourceParentId (only updated if not empty; d:0 can be used to move the resource to the root folder)
   • ResourceSyncState (only applicable for folder resources; only updated if set to 1 (ssSynced) or 2 (ssNotSynced))
   • ResourceTags
3. For file resources, you may set LocalFile or ResourceData if you wish to update the file data on the server. (Refer to UploadFile for more information about simple vs. resumable uploads and encrypting the file data before uploading.)
   • Like with UploadFile, the ClientModifiedTime configuration setting may be set when updating file data.
4. Finally, call this method to update the resource.

UploadFile Method (Box Control)

Uploads a new file resource.

Syntax

boxcontrol.UploadFile FileName, ParentId

Remarks

This method uploads a new file resource named FileName to the folder specified by ParentId. The Id of the newly-created file resource is returned.

FileName must be no longer than 255 characters; may not contain /, \, non-printable ASCII characters, or trailing whitespace; and cannot be one of the special names . or ...

ParentId can be empty, in which case the file is uploaded to the root folder.

The ClientCreatedTime and ClientModifiedTime configuration settings may be set before calling this method to submit those timestamps along with the file data.

If LocalFile is set the file will be uploaded from the specified path. If LocalFile is not set the data in ResourceData will be used.

To encrypt the file before uploading it, set EncryptionAlgorithm and EncryptionPassword.

Upload Notes

Box offers two ways to upload a file. For smaller files a simple upload option is provided to upload data in one request. This is the default option. For larger files (must be larger than 20 MB), uploads can be fragmented into multiple pieces, allowing resuming of uploads that may be interrupted.

Simple

By default the control uses the simple upload mechanism. When doing a simple upload, the HashSimpleUploads setting is applicable. box.LocalFile = "../MyFile.zip"; box.UploadFile("MyFile.zip", "");

Resumable

To enable resumable uploads set UseResumableUpload to . This is recommended for large files (must be larger than 20 MB). The control will automatically fragment the specified file into smaller pieces and upload each individually.

When UseResumableUpload is set to and UploadFile is called, a resumable upload session is started by the control. ResumeURL is populated with a URL identifying the session (this value may be needed for additional operations if the upload does not complete normally).

During a resumable upload, the FragmentComplete event fires after each fragment is uploaded to indicate overall progress. The control also updates StartByte as necessary to indicate the current offset in the file.

If the upload is interrupted for any reason, resuming it is easy. First, verify that ResumeURL is populated (if the same instance of the control is used, it should already be populated, and no special action should be needed). Call PollUploadStatus to populate the correct values for StartByte and UploadFragmentSize. Then call UploadFile again to resume the upload at the specified StartByte offset.

Note that if the upload is not resumed after some time the upload session will expire. PollUploadStatus may be used to check the status of a resumable upload, including when it will expire (which is stored in the UploadExpDate configuration setting). An interrupted upload can be aborted explicitly using the AbortUpload method. box.LocalFile = "../MyFile.zip"; box.UploadFile("MyFile.zip", ""); //The transfer is interrupted and UploadFile() above fails. Later, resume the download. //Using the same instance StartByte and ResumeURL are already populated from the previous //upload attempt. box.UploadFile("MyFile.zip", "");

EndTransfer Event (Box Control)

This event fires when a document finishes transferring.

Syntax

Sub boxcontrol_EndTransfer(Direction As Integer)

Remarks

The EndTransfer event is fired when the document text finishes transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Error Event (Box Control)

Fired when information is available about errors during data delivery.

Syntax

Sub boxcontrol_Error(ErrorCode As Integer, Description As String)

Remarks

The Error event is fired in case of exceptional conditions during message processing. Normally the control fails with an error.

The ErrorCode parameter contains an error code, and the Description parameter contains a textual description of the error. For a list of valid error codes and their descriptions, please refer to the Error Codes section.

FragmentComplete Event (Box Control)

Fires after each fragment of a resumable upload is completed.

Syntax

Sub boxcontrol_FragmentComplete(FragmentNumber As Integer, FragmentCount As Integer, Interrupt As Boolean)

Remarks

When UseResumableUpload is and UploadFile is called, this event will fire after each fragment is uploaded, providing an indication of overall upload progress.

FragmentNumber is the number of the current fragment that has completed. This value starts at 1.

FragmentCount is the total number of fragments that will be uploaded.

Interrupt can be set to to interrupt the upload. The upload may be resumed later.

Header Event (Box Control)

This event is fired every time a header line comes in.

Syntax

Sub boxcontrol_Header(Field As String, Value As String)

Remarks

The Field parameter contains the name of the HTTP header (which is the same as it is delivered). The Value parameter contains the header contents.

If the header line being retrieved is a continuation header line, then the Field parameter contains "" (empty string).

Log Event (Box Control)

This event fires once for each log message.

Syntax

Sub boxcontrol_Log(LogLevel As Integer, Message As String, LogType As String)

Remarks

This event fires once for each log message generated by the control. The verbosity is controlled by the LogLevel setting.

LogLevel indicates the level of message. Possible values are as follows:

The value 1 (Info) logs basic information, including the URL, HTTP version, and status details.

The value 2 (Verbose) logs additional information about the request and response.

The value 3 (Debug) logs the headers and body for both the request and response, as well as additional debug information (if any).

Message is the log entry.

LogType identifies the type of log entry. Possible values are as follows:

• "Info"
• "RequestHeaders"
• "ResponseHeaders"
• "RequestBody"
• "ResponseBody"
• "ProxyRequest"
• "ProxyResponse"
• "FirewallRequest"
• "FirewallResponse"

MetadataList Event (Box Control)

Fires once for each metadata item when listing a resource metadata.

Syntax

Sub boxcontrol_MetadataList(Name As String, Value As String, ValueType As Integer, ContainerScope As String, ContainerSchema As String, ResourceId As String)

Remarks

This event fires once for each metadata item returned when ListMetadata is called.

Name is the name of the metadata item.

Value is the value of the metadata item.

ValueType is the value of the metadata item. Possible values, and their corresponding Box types, are:

ContainerScope is the scope that the metadata item's container resides in.

ContainerSchema is the schema of the metadata item's container.

ResourceId is the Id of the resource that the metadata is associated with.

Note that metadata is only usable on resources owned by paid Box accounts.

Progress Event (Box Control)

Fires during an upload or download to indicate transfer progress.

Syntax

Sub boxcontrol_Progress(Direction As Integer, BytesTransferred As Long64, TotalBytes As Long64, PercentDone As Integer)

Remarks

This event fires during an upload or download to indicate the progress of the transfer of the entire request. By default, this event will fire each time PercentDone increases by one percent; the ProgressStep configuration setting can be used to alter this behavior.

Direction indicates whether the transfer is an upload (0) or a download (1).

BytesTransferred reflects the number of bytes that have been transferred so far, or 0 if the transfer is starting (however, see note below).

TotalBytes reflects the total number of bytes that are to be transferred, or -1 if the total is unknown. This amount includes the size of everything in the request like HTTP headers.

PercentDone reflects the overall progress of the transfer, or -1 if the progress cannot be calculated.

Note: By default, the control tracks transfer progress absolutely. If a transfer is interrupted and later resumed, the values reported by this event upon and after resumption will account for the data that was transferred before the interruption.

For example, if 10MB of data was successfully transferred before the interruption, then this event will fire with a BytesTransferred value of 10485760 (10MB) when the transfer is first resumed, and then continue to fire with successively greater values as usual.

This behavior can be changed by disabling the ProgressAbsolute configuration setting, in which case the control will treat resumed transfers as "new" transfers. In this case, the BytesTransferred parameter will always be 0 the first time this event fires, regardless of whether the transfer is new or being resumed.

ResourceList Event (Box Control)

Fires once for each resource returned when listing resources or versions.

Syntax

Sub boxcontrol_ResourceList(Id As String, Name As String, Description As String, ResourceType As Integer, CreatedTime As String, ModifiedTime As String, Size As Long64, VersionId As String, ETag As String, Hash As String, Trashed As Boolean, SharedLink As String)

Remarks

This event fires once for each resource returned when ListResources, GetResourceInfo, Search, or ListVersions is called.

Id is the Id of the resource.

Name is the name of the resource.

Description is a description of the resource.

ResourceType reflects the resource's type. Possible values are:

CreatedTime and ModifiedTime reflect the resource's creation and last modified timestamps. Timestamps are formatted according to RFC 3339.

Size is the size of the resource (for folders, their contents' total size), in bytes.

VersionId is the version Id of the file resource. Not applicable for file resources. (Note that Box only tracks file versions for paid accounts.)

ETag is the ETag of the resource.

Hash holds a SHA1 hash of the file resource's content. Not applicable for folder resources.

Trashed indicates whether the resource is in the trash.

SharedLink is the shared link URL for the resource. May be empty if the resource doesn't have a shared link active.

SSLServerAuthentication Event (Box Control)

Fired after the server presents its certificate to the client.

Syntax

Sub boxcontrol_SSLServerAuthentication(CertEncoded As String, CertSubject As String, CertIssuer As String, Status As String, Accept As Boolean)

Remarks

During this event, the client can decide whether or not to continue with the connection process. The Accept parameter is a recommendation on whether to continue or close the connection. This is just a suggestion: application software must use its own logic to determine whether or not to continue.

When Accept is False, Status shows why the verification failed (otherwise, Status contains the string OK). If it is decided to continue, you can override and accept the certificate by setting the Accept parameter to True.

SSLStatus Event (Box Control)

Fired when secure connection progress messages are available.

Syntax

Sub boxcontrol_SSLStatus(Message As String)

Remarks

The event is fired for informational and logging purposes only. This event tracks the progress of the connection.

StartTransfer Event (Box Control)

This event fires when a document starts transferring (after the headers).

Syntax

Sub boxcontrol_StartTransfer(Direction As Integer)

Remarks

The StartTransfer event is fired when the document text starts transferring from the server to the local host.

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

Transfer Event (Box Control)

This event is fired while a document transfers (delivers document).

Syntax

Sub boxcontrol_Transfer(Direction As Integer, BytesTransferred As Long64, PercentDone As Integer, Text As String)

Remarks

The Text parameter contains the portion of the document text being received. It is empty if data are being posted to the server.

The BytesTransferred parameter contains the number of bytes transferred in this Direction since the beginning of the document text (excluding HTTP response headers).

The Direction parameter shows whether the client (0) or the server (1) is sending the data.

The PercentDone parameter shows the progress of the transfer in the corresponding direction. If PercentDone can not be calculated the value will be -1.

Note: Events are not re-entrant. Performing time-consuming operations within this event will prevent it from firing again in a timely manner and may affect overall performance.

Config Settings (Box Control)
